Blood from blood cupping is not necessarily waste blood. Blood cupping is a therapeutic method in traditional Chinese medicine, and the main operation is to release blood by stabbing, that is, after sterilizing the part to be operated and releasing blood by needling, the blood is extracted from the part by using a fire pot or air pot. The blood released by blood cupping is the blood released from the acupuncture site, not necessarily waste blood. The main effects of blood cupping are to activate blood circulation, remove blood stasis, clear heat and toxins (remove heat and toxins from the body), promote local blood circulation, and dredge the meridians. Therefore, the blood produced by this treatment is not necessarily waste blood in the body; it is possible that the normal blood in that part of the body is being released. However, if the blood cupping operation is to release a certain portion of stagnant blood, then the blood released is waste blood. To summarize, the blood from blood cupping is not necessarily waste blood, and any discomfort should go to the hospital in time.
